Investigating the effectiveness of iron nanoparticles synthesized by green synthesis method in chemoradiotherapy of colon cancer.

Current methods of colon cancer treatment, especially chemotherapy, require new treatment methods due to adverse side effects. One important area of interest in recent years is the use of nanoparticles as drug delivery vehicles since several studies have revealed that they can improve the target specificity of the treatment thus lowering the dosage of the drugs while preserving the effectiveness of the treatment thus reducing the side effects. The use of traditional medicine has also been a favorite topic of interest in recent years in medical research, especially cancer research. In this research work, the green synthesis of Fe nanoparticles was carried out using Mentha spicata extract and the synthesized nanoparticles were identified using FT-IR, XRD, FE-SEM and EDS techniques. Then the effect of Mentha spicata, Fe nanoparticles, and Mentha spicata -loaded Fe nanoparticles on LS174t colon cancer cells, and our result concluded that all three, especially Mentha spicata -loaded Fe nanoparticles, have great cytotoxic effects against LS174t cells, and exposure to radiotherapy just further intensified these results. The in vitro condition revealed alterations in the expression of pro-apoptotic BAX and anti-apoptotic Bcl2, suggesting a pro-apoptotic effect from all three components, particularly the Mentha spicata-loaded Fe nanoparticles. After further clinical trials, these nanoparticles can be used to treat colon cancer.

Parasites of Stray Cats in Iran: A Parasitological and Histopathological Study.

Many zoonotic parasitic diseases, including Toxocara cati, may be spread by stray cat populations. This study aimed to determine the prevalence of parasites by performing parasitological and histopathological examinations on stray cats in Shiraz, Iran. A total of 106 stray cats from different geographical areas of Shiraz, southern Iran, were examined for the presence of parasites. The overall prevalence was found to be 83.02% (88/106), and eight parasites were found. The parasites included three genera of cestodes [Joyeuxiella echinorhynoides (52.83%), Taenia taeniaeformis (21.70%), and Dipylidium caninum (1.89%)], three nematodes [Physaloptera praeputialis (23.59%), Toxocara cati (15.09%), and Rictularia sp. (1.89%)], one protozoa [Isospora spp. (6.60%)], and one arthropod [Ctenocephalides felis (5.66%)]. The prevalence did not significantly differ between males and females. It did appear, nevertheless, that the age of cats may be regarded as a risk factor for these parasitic infections. Histopathological examination revealed some parasite-induced lesions in the intestine and stomach, including hyperemia, hemorrhage, mucosal destruction and inflammation. The lung tissues showed some histopathological lesions such as hemorrhage, edema, emphysema and mild inflammation, and dormant larvae were found in one tongue sample. The results of the present study showed that parasitic infections and, more importantly, T. cati are relatively prevalent in stray cats, and the people living in this area are at serious risk of this zoonotic disease. The cats in this region need to be monitored, and specific preventive measures should be developed by public health officials.

Potential of Autologous Adipose-Derived Mesenchymal Stem Cells in Peritoneal Fibrosis: A Pilot Study.

BACKGROUND: We aimed to determine the effects of systemic therapy with autologous adipose tissue derived mesenchymal stem cells (AD-MSCs) on different parameters of peritoneal function and inflammation in peritoneal dialysis (PD) patients. METHODS: We enrolled nine PD patients with ultrafiltration failure (UFF). Patients received 1.2±0.1×106 cell/kg of AD-MSCs via cubital vein and were then followed for six months at time points of baseline, 3, 6, 12, 16 and 24 weeks after infusion. UNI-PET was performed for assessment of peritoneal characteristics at baseline and weeks 12 and 24. Systemic and peritoneal levels of tumor necrosis factor α (TNF-α), interleukin-6(IL-6), IL-2 and CA125 (by ELISA) and gene expression levels of transforming growth factor beta (TGF-ß), smooth muscle actin (𝛼-SMA) and fibroblast-specific protein-1 (FSP-1) in PD effluent derived cells (by quantitative real-time PCR) were measured at baseline and weeks 3, 6, 12, 16 and 24. RESULTS: Slight improvement was observed in the following UF capacity indices: free water transport (FWT, 32%), ultrafiltration - small pore (UFSP, 18%), ultrafiltration total (UFT, 25%), osmotic conductance to glucose (OCG, 25%), D/P creatinine (0.75 to 0.70), and Dt/D0 glucose (0.23 to 0.26). There was a slight increase in systemic and peritoneal levels of CA125 and a slight decrease in gene expression levels of TGF-ß, α-SMA and FSP-1 that was more prominent at week 12 and vanished by the end of the study. CONCLUSION: Our results for the first time showed the potential of MSCs for treatment of peritoneal damage in a clinical trial. Our results could be regarded as hypothesis suggestion and will need confirmation in future studies.

First report of deutonymph Myianoetus, Willmann, 1937 (Acari: Astigmata) from Iran.

Myianoetus is a Histiostomatidae mites that are phoretic on flies. The relation between flies and phoretic mites is considered to be of potential value in forensic studies, as the development of flies associated with decomposing human remains. So, they may useful in determining the time of death of an individual. This study represents the first records of Myianoetus muscarum deutonymph phoretic on adult Musca domestica in Iran. Further studies are needed to find any relation between phoretic mites and flies.

Molecular characterization and phylogenetic analysis of Linguatula serrata isolated from camels, sheep and goats in Iran.

Linguatula serrata is an important zoonotic parasite with worldwide distribution. The objective of the present study was to investigate the molecular characterization and phylogenetic analysis of nymphal stage of L. serrata from camels, goats and sheep in Iran. The mesenteric lymph nodes were collected from various ruminants including goats, sheep and camels at Isfahan and Shiraz slaughterhouses and the nymphs were identified using morphological characteristics. After DNA extraction, the 18 S rRNA and Cox1 genes were amplified by polymerase chain reaction. The sequencing of the genes was conducted using specific primers and a capillary DNA analyzer. The comparison of amplified sequences with existing data confirmed the presence of L. serrata with 99.6-100% nucleotide sequence similarity. Based on 18 S rRNA and Cox1 sequences, two isolates collected from sheep revealed 100% and 99.9% sequence identity, respectively. Also, three isolates from camel had 99.64-100% and 99.7-100% homology. Two isolates from sheep had 100% identity in their 18SrRNA gene and were categorized together, but showed 99.9% similarity in the Cox1 gene, not clustering together. Phylogenetic analysis of the Cox1 gene classified nearly all the isolates into L. arctica clade. It can be concluded that 18 S rRNA and Cox1 genes sequencing can be a proper method for the analysis of phylogenetic relationships of L. serrata among different hosts in different parts of Iran, possibly helpful for infection control and prevention.

Effects of concurrent training and CoQ10 on neurotrophic factors and physical function in people with Multiple Sclerosis: a pilot study.

The present study aimed to investigate the effects of 8-week of coenzyme Q10 (CoQ10) supplementation alone or combined with concurrent training (CT) on functional capacity, serum brain derived neurotrophic factor (BDNF) and nerve growth factor (NGF) in multiple sclerosis (MS) patients. Our hypothesis is that CT promotes improvements in the studied outcomes with higher results for the combination of CT and CoQ10. Randomized placebo-controlled trial. Twenty-eight patients with MS were randomly divided into 4 groups: CT+placebo, CT+CoQ10, CoQ10 and placebo. CT involved two resistance training sessions and one aerobic training session per week. CoQ10 was supplemented with 200 mg daily. Serum levels of BDNF, NGF and functional tests [timed up and go (TUG), 6-min walk (6MW), chest press, lateral pull down, leg extension, and lying leg curls one repetition maximum] were measured before and after the intervention period. CT+placebo and CT+CoQ10 significantly improved performance in TUG, 6MW, chest press, lateral pull down, leg extension, and lying leg curls, with superior results to both CoQ10 and placebo groups. Changes in TUG for CT+placebo were significantly higher than CT+CoQ10 (p<0.05). There were no significant differences in NGF and BDNF among the four groups (p >0.05). CT improves physical abilities in patient with MS, regardless CoQ10 supplementation. CT should be recommended for MS patients to increase functional capacity, but there seems to be no benefit in supplementing CoQ10.

Comparison of Ticagrelor and Clopidogrel in Elective Coronary Stenting: A Double Blind Randomized Clinical Trial.

Background: Dual antiplatelet therapy with a P2Y12 inhibitor (e.g., clopidogrel and ticagrelor) and aspirin is recommended for at least one year after percutaneous coronary intervention (PCI) to prevent further myocardial infarction and stent thrombosis as the major adverse effects of PCI. Methods: This randomized clinical trial was conducted from October 2022 to March 2023. Patients who had undergone elective PCI were included in the study. Patients were randomized into two different groups. One group took ASA 80 mg and clopidogrel 75 mg once daily, while the other took ASA 80 mg once daily and ticagrelor 90 mg twice daily. After six months of close follow-up, patients were asked to score their dyspnea on a 10-point Likert scale. They were also asked about dyspnea on exertion, paroxysmal nocturnal dyspnea (PND), bleeding, and the occurrence of major adverse cardiovascular events (MACEs). Results: 223 patients were allocated to the clopidogrel group and 214 to the ticagrelor group. In the ticagrelor group, 95 patients (44.3%) reported dyspnea at rest, compared with only 44 patients (19.7%) in the clopidogrel group (P < 0.001). MACEs occurred in 7 patients (2.8%) in the ticagrelor group, compared with 16 (7.6%) in the clopidogrel group (P = 0.031). Eight patients (3.8%) reported bleeding with ticagrelor, as did seven (3.2%) with clopidogrel (P = 0.799). Conclusions: New-onset dyspnea was recorded more frequently with ticagrelor than clopidogrel, yet fewer MACEs occurred with ticagrelor (ClinicalTrials.gov number: NCT05858918).

Evaluation the effects of red yeast rice in combination with statin on lipid profile and inflammatory indices; a randomized clinical trial.

BACKGROUND: Dyslipidemia is a prominent cause of cardiovascular disease as it leads to inflammation and plaque deposition within arteries. Treatment includes lifestyle modifications and lipid-lowering medications. We aimed to assess the therapeutic effects of red yeast rice (RYR) alongside statin therapy. METHODS: This triple-blind randomized clinical trial involved 92 dyslipidemia patients and was performed in 2019. Standard laboratory tests were used to assess the serum LDL cholesterol (LDL-C), HDL cholesterol (HDL-C), total cholesterol, triglyceride (TG), and high sensitivity C-reactive protein (hs-CRP) levels. Subsequently, patients randomly received one daily RYR or placebo tablet for 1 month beside routine single statin therapy. Subsequently, blood tests were repeated and compared against the baseline. Liver function tests were also requested. RESULTS: Total cholesterol significantly (P = 0.019) decreased in the treatment group (- 10.2 mg/dL) compared with the placebo group (- 1.3 mg/dL). HDL cholesterol decreased by 2.19 mg/dL in the treatment group but increased by 0.53 mg/dL in the treatment group (P = 0.083). LDL cholesterol declined in both placebo (- 5.09) and treatment (- 0.73) groups (P = 0.187). TG increased by about 7 mg/dL in the treatment group but fell by roughly 1 mg/dL in the placebo group (P = 0.386). Hs-CRP increased by 0.28 mg/dL in the treatment group but decreased by 0.09 mg/dL in the placebo group (P = 0.336). CONCLUSIONS: We found that adding RYR (Lesstat®) to statin medications significantly decreases total cholesterol. However, no significant effect was seen on other lipid profile components or Hs-CRP. Finally, we showed that RYR is safe to add to statins considering liver function (clinicaltrials.gov: NCT05095480).

Active immunotherapy against pathogenic Cis pT231-tau suppresses neurodegeneration in traumatic brain injury mouse models.

Traumatic brain injury (TBI), characterized by acute neurological impairment, is associated with a higher incidence of neurodegenerative diseases, particularly chronic traumatic encephalopathy (CTE), Alzheimer's disease (AD), and Parkinson's disease (PD), whose hallmarks include hyperphosphorylated tau protein. Recently, phosphorylated tau at Thr231 has been shown to exist in two distinct cis and trans conformations. Moreover, targeted elimination of cis P-tau by passive immunotherapy with an appropriate mAb that efficiently suppresses tau-mediated neurodegeneration in severe TBI mouse models has proven to be a useful tool to characterize the neurotoxic role of cis P-tau as an early driver of the tauopathy process after TBI. Here, we investigated whether active immunotherapy can develop sufficient neutralizing antibodies to specifically target and eliminate cis P-tau in the brain of TBI mouse models. First, we explored the therapeutic efficacy of two different vaccines. C57BL/6 J mice were immunized with either cis or trans P-tau conformational peptides plus adjuvant. After rmTBI in mice, we found that cis peptide administration developed a specific Ab that precisely targeted and neutralized cis P-tau, inhibited the development of neuropathology and brain dysfunction, and restored various structural and functional sequelae associated with TBI in chronic phases. In contrast, trans P-tau peptide application not only lacked neuroprotective properties, but also contributed to a number of neuropathological features, including progressive TBI-induced neuroinflammation, widespread tau-mediated neurodegeneration, worsening functional deficits, and brain atrophy. Taken together, our results suggest that active immunotherapy strategies against pathogenic cis P-tau can halt the process of tauopathy and would have profound clinical implications.

The effect of calcium and vitamin D supplements on blood pressure in postmenopausal women: myth or reality?

Hypertension is a highly prevalent disease with serious cardiovascular and renal complications. Many studies have demonstrated a weak correlation between the consumption of calcium (or calcium plus vitamin D) and blood pressure, suggesting that calcium supplements might reduce blood pressure. However, the results to date remain controversial. In this study, we assessed the effect of calcium and vitamin D supplementation on the blood pressure of postmenopausal women with hypertension as a population group in which the use of calcium supplements is prevalent. This triple-blind randomized clinical trial enrolled 98 women of postmenopausal age with hypertension in 2019. The study period was 8 weeks with close follow-up. We used 24-h ambulatory blood pressure monitoring to record the initial and final blood pressure in all participants. The changes in both the mean systolic (p = 0.047) and diastolic blood pressure (p = 0.015) were suggestive of an increase in blood pressure after consuming calcium and vitamin D supplements. Among patients who had been using calcium channel blockers, calcium and vitamin D supplementation caused a notable increase compared to baseline systolic (p = 0.019) and diastolic blood pressures (p = 0.001). The present results differ from those of previous studies. This suggests that calcium supplementation for postmenopausal women with hypertension requires the close observation of blood pressure to prevent any further increase, especially in women who are being treated with calcium channel blockers (clinicaltrial.gov registration: NCT04618952).

Kidney organoids: current knowledge and future directions.

The kidney is a highly complex organ in the human body. Although creating an in vitro model of the human kidney is challenging, tremendous advances have been made in recent years. Kidney organoids are in vitro kidney models that are generated from stem cells in three-dimensional (3D) cultures. They exhibit remarkable degree of similarities with the native tissue in terms of cell type, morphology, and function. The establishment of 3D kidney organoids facilitates a mechanistic study of cell communications, and these organoids can be used for drug screening, disease modeling, and regenerative medicine applications. This review discusses the cellular complexity during in vitro kidney generation. We intend to highlight recent progress in kidney organoids and the applications of these relatively new technologies.

Molecular characterization of quinolone resistance and antimicrobial resistance profiles of Klebsiella pneumoniae and Escherichia coli isolated from human and broiler chickens.

This study characterized quinolone (Q) resistance determinants in a series of Klebsiella pneumoniae (n = 26) and Escherichia coli (n = 19) isolates of human and animal origin. The presence of plasmid-mediated quinolone resistance (PMQR) and carabpenemase genes was examined by PCR. The quinolone resistance-determining regions (QRDRs) of gyrA and parC genes were sequenced. Thirty-three isolates had ciprofloxacin MIC≥8 mg/l. About 34.6% and 10.5% of K. pneumoniae and E. coli isolates were ESBL producers respectively. The PMQR genes were detected in 77% (n = 35) of isolates. The oqxAB was the most prevalent PMQR gene being identified in all K. pneumoniae isolates, followed by aac(6')-Ib-cr (34.6%), qnrS (23%) and qnrB (7.7%). The most frequently detected gene among E. coli isolates was qnrS (36.8%) followed by aac(6')-Ib-cr (10.5%) and qepA (5.2%). All Q resistant isolates harbored amino acid substitutions in both GyrA and ParC QRDRs. High prevalence of PMQR genes among food-producing animal isolates is an issue of great concern.

Effects of High- or Moderate-intensity Rosuvastatin on 1-year Major Adverse Cardiovascular Events Post-percutaneous Coronary Intervention.

Background: Although statins decrease mortality in coronary artery disease, the effect of high-dose statins and duration of therapy post-percutaneous coronary intervention (PCI) is not well addressed. Aim: To determine the effective dose of statin to prevent major adverse cardiovascular events (MACEs), such as acute coronary syndrome, stroke, myocardial infarction, revascularisation and cardiac death, after PCI in patients with chronic coronary syndrome. Methods: In this randomised, double-blind clinical trial, all chronic coronary syndrome patients with a recent history of PCI were randomly divided into two groups after 1 month of high-dose rosuvastatin therapy. Over the next year, the first group received rosuvastatin 5 mg daily (moderate intensity), while the second received rosuvastatin 40 mg daily (high intensity). Participants were evaluated in terms of high-sensitivity C-reactive protein and MACEs. Results: The 582 eligible patients were divided into group 1 (n=295) and group 2 (n=287). There was no significant difference between the two groups in terms of sex, age, hypertension, diabetes, smoking, previous history of PCI or history of coronary artery bypass grafting (p>0.05). There were no statistically significant differences in MACE and high-sensitivity C-reactive protein after 1 year between the two groups (p=0.66). Conclusion: The high-dose group had lower LDL levels. However, given the lack of association between high-intensity statins and MACEs in the first year after PCI among chronic coronary syndrome patients, the use of moderate-intensity statins may be as effective as high-intensity statins, and treatment based on LDL targets may suffice.

Evaluation of in vitro activity of ceftaroline on methicillin resistant Staphylococcus aureus blood isolates from Iran.

BACKGROUND AND OBJECTIVES: Ceftaroline (CPT) is a novel cephalosporin with potent activity against methicillin-resistant Staphylococcus aureus (MRSA). Despite its recent introduction, CPT resistance in MRSA has been described worldwide. We aimed in the current study to evaluate the in vitro activity of CPT against 91 clinical MRSA and 3 MSSA isolates. MATERIALS AND METHODS: Susceptibility of isolates to CPT was tested using E-test and disk diffusion (DD) method. The nucleotide sequence of the mecA gene and molecular types of isolates with reduced susceptibility to CPT were further studied to identify resistance conferring mutations in PBP2a and the genetic relatedness of the isolates respectively. RESULTS: Overall, 92.5% of isolates were found to be CPT susceptible (MICs≤1mg/l) and 7 MRSA isolates were characterized with MIC=2mg/l and categorized as susceptible dose dependent. Compared to E-test, DD revealed a categorical agreement rate of 93.6% and the obtained rates for minor, major /very major error were found to be 6.3% and 0% respectively. The MRSA isolates with increased CPT MICs (n=7), belonged to spa types t030 (n=6) and t13927 (n=1) and all carried N146K substitution in PBP2a allosteric domain, except for one isolate which harbored a wild-type PBP2a. CONCLUSION: While resistance to CPT was not detected we found increased CPT MICs in 7.69% of MRSA isolates. Reduced susceptibility to CPT in the absence of mecA mutations is indicative of contribution of secondary chromosomal mutations in resistance development.

COVID-19 and Immunosuppressive Therapy in Ocular Inflammatory Disease, a Telemedicine Survey.

Purpose: Determine the risk of immunomodulatory therapy (IMT) for COVID-19 infection morbidity.Method: A telemedicine survey on patients of a referral uveitis clinic was performed. Signs of infection, habits, and hospitalizations during the 7 months of the COVID-19 pandemic prior to the study date were recorded. Suggestive findings in chest CT scan and/or positive RT-PCR were considered as confirmed COVID-19 infection while those with only suggestive symptoms were considered as suspected cases. Risk factors including sanitary measures and IMT were compared between patients with confirmed cases and patients without infection.Result: 694 patients were included. Eight patients were identified as confirmed cases and 22 patients as suspected cases of COVID-19 infection. Close contact with infected persons was the only significant risk factor for contracting COVID-19.Conclusion: Using IMT did not affect hospitalization and/or ICU admission and can thus be continued during the pandemic, provided that instructions for preventive measures are followed.

Molecular Characterization of Tigecycline Non-Susceptibility among Extensively Drug-Resistant Acinetobacter baumannii Isolates of Clinical Origin.

INTRODUCTION: Tigecycline (TGC) is one of the last-resort therapeutic agents for treating infections caused by extensively drug resistant Acinetobacter baumannii isolates. Although resistance to TGC is not common, non-susceptible A. baumannii (NSAB) isolates have been described. In the current study, we aimed to assess the molecular mechanisms mediating TGC non-susceptibility in 5 clinical isolates of A. baumannii with reduced susceptibility to TGC. METHODS: Susceptibility of isolates to TGC as well as various classes of antibiotics was evaluated by broth dilution and disk diffusion methods, respectively. The presence of tetX and tetX1 genes was investigated by PCR. The nucleotide sequences of adeR and adeS genes were assessed by PCR amplicon sequencing. To evaluate the association between reduced susceptibility to TGC and upregulation of AdeABC efflux pump, transcriptional level of adeB gene was quantified by RT-qPCR analysis. RESULTS: All 5 TGC-NSAB isolates had a TGC MIC of ≥4 mg/L and were resistant to all antimicrobials tested by disk diffusion method except for minocycline and doxycycline for which a susceptibility rate of 40% and 20% was observed, respectively. The tetX/X1 genes were not detected in any isolates. All TGC non-susceptible isolates harbored genetic alterations in the adeRS operon, including AdeS G186V, N268H, and D60N and AdeR A136V and V120I substitutions among, which G186V and D60N were predicted by PROVEAN tool analysis as inactivating alterations. Reduced TGC susceptibility was associated with upregulation of AdeABC efflux pump in all TGC non-susceptible isolates. CONCLUSION: It can be concluded from our results that reduced susceptibility to TGC in the studied isolates was mainly mediated by genetic alterations in the AdeRS system, which resulted in overexpression of AdeABC efflux pump. Emergence of TGC non-susceptibility among isolates that had not been previously exposed to TGC is an issue of great concern.

Safety assessment of genetically modified rice expressing Cry1Ab protein in Sprague-Dawley rats.

Rice is considered one of the most important staple food crops. Genetically modified (GM) Bt rice, harbored cry1Ab gene expressing the insect-resistance protein has been developed to resistance to the insects. In this study, we assessed the safety of the GM Bt rice on Sprague-Dawley rats for 90 days. Totally, 120 rats in both sexes were used for three different diets, including 50% GM Bt rice, feeding with 50% rice, and standard feeding. Each 40 SD rats including 20 males and 20 females were considered as each diet. The clinical variables such as body weight and food consumption were measured and a range of clinical tests was examined, including hematology, serum chemistry parameters, urinalysis profile, thyroid, and sex hormone levels. Pathological assessments were also done. The results showed that the mean weekly feed utilization (%) had no significant difference among the studied groups. Also, blood biochemistry, hematological parameters, urine analysis, and hormonal levels had no significant differences among the groups. However, alanine aminotransferase was less in males versus female feeding with GM Bt rice. No histopathological changes were observed among the groups. In conclusion, this study demonstrated that GM Bt rice had no obvious adverse effects on rats' health.

Kidney Regeneration: Stem Cells as a New Trend.

Renal disease is a major worldwide public health problem that affects one in ten people. Renal failure is caused by the irreversible loss of the structural and functional units of kidney (nephrons) due to acute and chronic injuries. In humans, new nephrons (nephrogenesis) are generated until the 36th week of gestation and no new nephron develops after birth. However, in rodents, nephrogenesis persists until the immediate postnatal period. The postnatal mammalian kidney can partly repair their nephrons. The kidney uses intrarenal and extra-renal cell sources for maintenance and repair. Currently, it is believed that dedifferentiation of surviving tubular epithelial cells and presence of resident stem cells have important roles in kidney repair. Many studies have shown that stem cells obtained from extra-renal sites such as the bone marrow, adipose and skeletal muscle tissues, in addition to umbilical cord and amniotic fluid, have potential therapeutic benefits. This review discusses the main mechanisms of renal regeneration by stem cells after a kidney injury.

Transplantation of Mouse Induced Pluripotent Stem Cell-Derived Podocytes in a Mouse Model of Membranous Nephropathy Attenuates Proteinuria.

Injury to podocytes is a principle cause of initiation and progression of both immune and non-immune mediated glomerular diseases that result in proteinuria and decreased function of the kidney. Current advances in regenerative medicine shed light on the therapeutic potential of cell-based strategies for treatment of such disorders. Thus, there is hope that generation and transplantation of podocytes from induced pluripotent stem cells (iPSCs), could potentially be used as a curative treatment for glomerulonephritis caused by podocytes injury and loss. Despite several reports on the generation of iPSC-derived podocytes, there are rare reports about successful use of these cells in animal models. In this study, we first generated a model of anti-podocyte antibody-induced heavy proteinuria that resembled human membranous nephropathy and was characterized by the presence of sub-epithelial immune deposits and podocytes loss. Thereafter, we showed that transplantation of functional iPSC-derived podocytes following podocytes depletion results in recruitment of iPSC-derived podocytes within the damaged glomerulus, and leads to attenuation of proteinuria and histological alterations. These results provided evidence that application of iPSCs-derived renal cells could be a possible therapeutic strategy to favorably influence glomerular diseases outcomes.
